This bobbin is not shown.

, By the means herein described, which form. a part of the presentinvention, the filaments are twisted before they are wound, and anyfilaments whichmay be broken will be caught by an adjacent filament orfilaments and stopping the apparatus. This propencatching of a. broken.filament'i's partly due to the revolutions ofthe cylinders and; theiraxial rotation and partly due to the fi 'otation of the the water orliquid is not absolutely necessary to the automatic reparation by thecatching of' the broken filament. Good results can be attained withoutit. v

The water in the open reservoir l-i maybe supplied and renewed in anyconvenient manner. It washes the filaments, and when desired it may bedrawn off by the removal of the plug 17.

In' the construction of Figs. 1 and 1'? just described the solution isused in successive charges; but it may be supplied in a .conti-nuousmanner to the mouthpieces. An apparatus for such continuous operation isillus trated in Fig. 2, which will now be described. The largegear-wheel 2", which carries the cylinder or cylinders 5 is in Fig. 2represented as a worm-wheel driven by a worm or screw 3 but this is notessential. inder or cylinders have no pistons or plungers, but receive,respectively, at the upper or their upper ends through suitablestufiingboxes the branch or the several branches .18 of a tubular spider18, the central branch of which has a bearing in a stufiing-box in atubular socketpiece 19, fixed in the frame. The solution for producingthe filaments of artificial silk is supplied to this socket-piece 19through a pipe 20, being supplied from some source under pressure andnot herein shown, and it passes down through the spider 18 and itsbranches to the cylinder or several cylinders, and thence to themouthpiece with one or several holes or several mouthpieces 6. In otherrespects the construction and operation are substantially the same asthat seen in Fig. 1.. v

In the constructions of Figs. 1 and 2 the direction in which thesolution flows through the apparatus is downward'vertically, the re- 7volving and rotating parts moving about vertical axle or axes, and thisis the preferred arrangement, as it permits the use of a simple openreservoir 14; but the apparatuses seen in The cyl- The construction ofFig. 3 is based on that of Fig. 2. 'an'd differs therefrom in substanceonly in the cylinders 5 having packed bearings in a disk 21, which formsa cover for the end of the reservoir 14, said cover having a packedbearing on the said reservoir. The latter has a filling-inlet 22 atitsupper side. Obviously this construction is not so simple as that seen inthe other views. Q

The words revolution""and revolving are herein used to express themovement of the words rotation and rotating to express the idea of themovement of a body about its own axis or center. I
